howto generate stunnel certificates?

[aparra <aparra@idecnet.com>]

I have look the man, but I can't see wowto make new certificates with 
openssl. I need to know, howto get a certificate for "myhost.mydomain" 
because the default one is for "stunnel" ther when I put a imap server 
over a stunnel conexion, the netscape din't stop on tell that the 
certificate is not for mydomain.

	Thank you all your help
